Plot

Shizuku Miyama (Riisa Naka) heard her father, who is a doctor, say that he doesn't have any expectations from his daughter because she is a girl. Since that time, Shizuku Miyama has strived to become a doctor to get recognition from her dad. She is now a medical resident and goes through training with four others. The 5 residents are all assigned to work at an emergency center for the next 3 months.

Meanwhile, Shizuku gets an order to work the night shift on her first day. During the seemingly quiet night, the hot line suddenly buzzes. Dr. Yayoi Kasumi orders Shizuku to treat incoming patient Natsuki (Rio Yamashita). Natsuki has attempted suicide several times and comes often to the emergency center. Shizuku is alarmed by Natsuki's crazy behavior and is unable to treat her. Shizuku is severely reprimanded by Yayoi, while more patients come into the emergency center.
